Since the infrared light signal emitted by the P-sensor is typically infrared light having a wavelength of less than or equal to 1000 nm. The transistor used by the amoled screen is sensitive to infrared light with a wavelength in the interval, and under the interference of the infrared light in the interval, the organic light-emitting material of the transistor corresponding to the P-sensor on the display screen is possibly damaged, so that the brightness of the area corresponding to the P-sensor on the display screen is reduced, the display effect is damaged, and the user experience is damaged.
In order to solve the above problem, in the technical solution provided in the embodiments of the present disclosure, by obtaining working parameters of a target display unit corresponding to a position of a distance sensor and a position on a display screen, the target display unit may be understood as a display unit that may affect or damage the display screen when the distance sensor performs distance measurement; the working time of the distance sensor is obtained, the compensation parameter of the distance sensor is obtained according to the working time, and the compensation parameter of the distance sensor is positively correlated with the working time, so that the compensation parameter of the distance sensor can reflect the influence or damage to the target display unit in the distance measurement process, the compensation parameter of the distance sensor compensates the working parameter of the target display unit, and the compensated working parameter of the target display unit is obtained.
